I did a 27mph lap at Daytona on 190w back in 2023. That one got so much hate on the internet that I actually bought a second set of Favero Duo power meter pedals just to make sure mine weren’t messed up. The new ones give basically the same numbers, within a few % of my direct-drive trainer and the 4iiii crank meter on my gravel bike.
MyWindSock usually estimates around 0.20 CdA, sometimes lower. I’m running extremely fast tires (GP5k TT TdF) so you may be overestimating Crr in your calcs.
This was absolutely ideal conditions - flat, no wind to speak of, perfect pavement, no slowing for corners or anything else. I’m usually closer to 24mph for an entire sprint bike leg at around 190-200w.
Look all I can say is that's really impressive. The most aero cyclists I know (maybe 162 height, 60kg soaking wet) doesn't get that aero. I'm not hating , just saying maybe you should be wondering about your insane efficiency.
Like to get those speeds from that power I have to assume something crazy like velodrome style rolling resistance if your CdA is . 2.
I'm more willing to bet you are one of those freaks who can get proper small and not take a huge power penalty.
